Solution Overview

Problem

Existing electronic converters face compatibility issues with LED modules of different types, leading to the need for specific matching and costly additional control units in simpler modules, making it inefficient to operate with both 'simple' and 'intelligent' LED modules.

Innovation Solution

A control method and circuit that differentiate between 'simple' and 'intelligent' LED modules based on voltage ranges on a data line, allowing for adaptive operation by detecting voltage values and using digital communication protocols as needed, eliminating the need for additional control units in simpler modules.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a control unit is added to simple LED modules to enable digital communication, then compatibility and control capability are improved, but device complexity and cost increase

Engineering Contradiction:
Improvecompatibility with electronic convertersVSAvoidcomplexity of LED module
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies local quality by providing different identification element types for different LED module categories. Simple LED modules use simple identification elements (analog interface only), while intelligent LED modules use intelligent identification elements (digital communication interface). This allows each module type to have the appropriate level of complexity for its specific application, resolving the contradiction between adaptability and device complexity.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The electronic converter is designed with universal compatibility to work with both simple and intelligent LED modules. The control unit can detect the type of identification element present and adapt its operation accordingly, allowing a single converter design to serve multiple module types without requiring additional control units in simple modules.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If different types of LED modules are used, then system flexibility and functionality are improved, but compatibility between electronic converters and LED modules deteriorates

Engineering Contradiction:
Improvevariety of LED module typesVSAvoidcompatibility between converter and module
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements preliminary action through the detection and identification process that occurs when an LED module is first connected to an electronic converter. The control unit detects the type of identification element (simple or intelligent) and automatically configures the communication protocol and control parameters accordingly. This preliminary identification ensures compatibility is established before normal operation begins, allowing diverse module types to work reliably with the converter.

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If simple identification elements are used in LED modules, then device complexity is reduced, but control capability and information handling deteriorate

Engineering Contradiction:
Improvesimplicity of LED moduleVSAvoidcontrol parameters information
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The patent segments the identification elements into two distinct categories: simple identification elements for simple LED modules and intelligent identification elements for intelligent LED modules. Simple identification elements provide basic analog interface functionality, while intelligent identification elements provide digital communication capabilities. This segmentation allows information needs to be matched to module complexity, resolving the contradiction between simplicity and information capability.

Inventive Principle:
Principle #1Segmentation
